Benefits of technology

The patent text describes a new type of display panel that prevents issues with brightness by making sure that each part of the panel is getting the same amount of work. This helps to create a more consistent and high-quality display.

Problems solved by technology

That is, the data lines and the scan lines may have different panel loads (such as RC delay) due to the difference in line length.
Accordingly, this may cause a luminance difference, thereby degrading display quality.

Embodiment Construction

[0026]In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of various exemplary embodiments. It is apparent, however, that various exemplary embodiments may be practiced without these specific details or with one or more equivalent arrangements. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring various exemplary embodiments.

[0027]In the accompanying figures, the size and relative sizes of layers, films, panels, regions, etc., may be exaggerated for clarity and descriptive purposes. Also, like reference numerals denote like elements.

[0028]When an element or layer is referred to as being “on,”“connected to,” or “coupled to” another element or layer, it may be directly on, connected to, or coupled to the other element or layer or intervening elements or layers may be present. When, however, an element or layer is re...

Abstract

A display device having a display area including a plurality of pixels and a non-quadrilateral shape, a first gate line in parallel with a first side of a virtual quadrilateral inscribed in the display area, a second gate line in parallel with a second side perpendicular to the first side of the virtual quadrilateral, a first data line in parallel with the first gate line; and a second data line in parallel with the second gate line.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority from and the benefit of Korean Patent Application No. 10-2014-0110968, filed on Aug. 25, 2014, which is hereby incorporated by reference for all purposes as if fully set forth herein.BACKGROUND[0002]Field[0003]Exemplary embodiments relate to a display panel, and more particularly, to a non-rectangular display panel.[0004]Discussion of the Background[0005]As portable devices (such as notebook computers, mobile phones, and portable media players (PMPs)) as well as devices for homes (such as TVs and monitors) become lighter and thinner, various flat panel displays are being widely used. There are various types of flat panel displays, including liquid crystal displays (LCDs), organic light-emitting displays, and electrophoretic displays. Generally, flat panel displays are rectangular. However, display panels having various shapes such as circular, oval, and polygonal shapes are being developed.[0006]A rectangul...
